DH-221M Retrievable Mechanical Packer

                    DH-221M Retrievable Mechanical Packer

 

Application：

Apply for zonal injection, extraction, leak finding, squeeze, acid treatment and well testing.

 

        Feature：

 

• Hydraulic anchor use stainless steel materials, which effectively prevent the phenomenon

hydraulic anchor claw rust and not back happened because of long time, poor water quality

in the sealing process.

 

• The elements are made of import modified hydrogenated butadiene acrylonitrile rubber

 

vulcanization, which has the characteristics: high temperature resistance, anti-aging,

 

resistance to high pressure difference. Once uncured after a long time in seal compression,

 

the recovery is good.

 

 

• Anchor claw and slip are set with hard alloy, which increased the bite of casing ability; it is

 

suitable for different styles.

 

 

• Slip and slip bowl are combined with wedge, which makes set or unsealing easy.

 

 

• Center tube is designed with internal the sand controls scream so that it is easy to

 

be recovery.

 

The design of packer is scientific; Production processing technology is controlled strictly,

good performance characteristics.
